Hopefully a future SP will include an easy button when replicating a table. Given that all the components are in place, an option to include archive data on a per table basis could be added to SLT. Wishful thinking I know, but why not just add another column to IUUC_REPL_TABSTG to manage this.
However, it's still a complex issue to solve when running SoH. Merging the data (on the fly) between two tables would require a lot of calculation or SQL engine overhead. It might just be that archiving is not necessary with SAP HANA but I am sure there are some that would disagree.
